Sequence Stratigraphic Correlation of Onshore and Offshore Bight Basin Successions : South

A new stratigraphic interpretation of Cretaceous sedimentary rocks from petroleum wells and water bores along the southern Australian coast. The record correlates onshore and offshore sections using biostratigraphic and seismic data, identifying four supersequences and potential source rocks. The Australian Ocean Data Network published this interpretation, last updated on 2026-06-05.

Use Cases

• Modeling basin evolution based on the described sequence stratigraphic framework and supersequences.
• Assessing hydrocarbon source rock potential based on identified organic-rich shale and marine facies.
• Correlating onshore and offshore geological sections using the provided biostratigraphic and seismic interpretations.
• Reconstructing paleo-depositional environments from the described transition from non-marine to marine deltaic conditions.

Strengths

• Maximum thickness of the succession is quantified at more than 357 meters in the Madura 1 well.
• Identifies specific Cretaceous supersequences (Bronze Whaler, Blue Whale-White Pointer, Tiger, Hammerhead).
• Correlates data from multiple source types: petroleum wells, stratigraphic holes, water bores, and seismic data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF and HTML formats, which may require extraction for computational analysis.
